Sam Walker is pushing to return for the Roosters' preliminary final against the Dolphins on Friday, less than a month after suffering a syndesmosis injury.
The halfback resumed running, kicking and contact-free training last week, prompting coach Trent Robinson to say he was "pretty confident" Walker would play.
A return would shift Daly Cherry-Evans back to five-eighth, potentially forcing Hugo Savala onto the bench after he covered that position and centre.
Walker has been a major-game performer this season, including Queensland's strongest displays in the opening two State of Origin matches.
"He's just been relentless in his recovery. It's been so great to watch him and to be honest it hasn't been surprising," Cherry-Evans said.
"He's an extremely competitive person. The team means a lot to him, the opportunity to play deep into finals means a lot to him."
Angus Crichton, who shared time in the injury ward with Walker, also endorsed the 22-year-old's comeback prospects.
"He is running, kicking and doing everything at training. It's pretty impressive. He is a big part of this team," Crichton said.
Cherry-Evans revived his own finals campaign with a try and three assists in the Roosters' 46-10 semi-final victory over Cronulla.
He had faced criticism after missing a field goal from directly in front during the 19-12 qualifying-final defeat against Penrith.
"You won't find anyone harder on my own game than myself," Cherry-Evans said.
"But if I carry my divots, I'm then not only putting myself out but my team out."
Quoting Ted Lasso, he added: "memory of a goldfish."
The 37-year-old will play his 378th NRL match on Friday and could finish his career if the Roosters lose.
He dismissed the significance of facing the Dolphins, whose Redcliffe roots include his father Troy, a former hooker.
Cherry-Evans also escaped suspension for tripping Teig Wilton, receiving a $1000 fine instead.
